Method of using cryptography with biometric verification on security authentication

Abstract

This invention represents a method of using cryptography with biometric verification on security authentication. The present invention relates to secure transmission of data or confidential information and, in particular, to cryptography technology that prevents the multiple passwords of keys lengthy, inconvenient and hard to be remembered or hidden. The method is used to perform security authentication by utilizing live biometric feature, which is non-transferable and unique among all humans, and operating the asymmetric key of cryptography technique for collation. Therefore, in the present invention, the method is capable of providing cryptography technology in conjunction with the biometric authorization to prevent that people don't like to carry private keys and using a single key only to perform authentication will reveal privacy or private information.

1 . A method of using cryptography with biometric verification on security authentication, comprising the steps of: 
 Utilizing physical immutable identification credentials of a user to perform authentication in conjunction with cryptography technology, and means for providing high security of transmission;    Generating a cryptographic key of the user using the DES algorithm from a user's host;    Encrypting means for using a public key of KDC to encrypt data including said cryptographic key and activated biometric features;    Transmitting means for transmitting said encrypted data from said host to said KDC for decryption; wherein    Decrypting said encrypted data using a private key of KDC to perform verification by collation and comparison; wherein    Collation means for collating said activated biometric features and digitized BIR stored on said KDC;    Comparison means for comparing said decrypted key with the original stored numbers on said KDC;    Approval means for getting approved from said verification, and for releasing the user's private key from said KDC;    Encoding said private key using said cryptographic key for transmitting to say host;    Retrieving said private key from said KDC, and for decoding said private key using said cryptographic key; and    Overcoming the need to carry, store or remember private keys for encryption/decryption.    
     
     
         2 . The method of  claim 1  wherein said user's host means for comprising a bank card, a credit card, a storage valued card, a magnetic strip card, an IC card, a smart card, an optical card, CD, DVD, a 2D bar code card, portable magnetic storage device, portable electronic memory device and portable mobile storage device.  
     
     
         3 . The method of using cryptography with biometric verification on security authentication as defined in  claim 1 , and further comprising: 
 Storing said private key of the user in a computer chip; and    Performing the BIR process and encryption/decryption processes of the user by the processor, which relates to calculation, collation and verification as a secured mechanism in the host.    
     
     
         4 . The method of  claim 3  wherein said computer chip means for comprising RISC CPU, CISC CPU, DSP, FPGA, CPLD, NET ASIC, Microprocessor, Micro controller and other chips with function calculation; and wherein the elements of said chips means for comprising system-on-a-chip (SOC), system-on-multiple-integrated-chips and system-on-multiple-chips.  
     
     
         5 . The method of  claim 1  wherein said biometric characteristics means for comprising fingerprint, voiceprint, face, iris, retina, palm print, palm shape, signature and other individual biometric characteristics according to the standard of International Biometric Industry Association (IBIA).
